Influence Experimental Study of Porous Media on Crude Oil Bubble Point

TANG Mi DU Jian-fen(Southwest Petroleum University,Chengdu 610500)  
This paper uses the constant composition expansion(CCE) of crude oil in full-diameter core.During the experiments,we have observed that there is no oil or gas coming out from pump and the volume increasing is not big,which has been raised in the process of depressurization,and showed that the flowing of oil and gas caused by depressurization happened in the core.Hence,for the high bubble point of crude oil studied in this paper,it is 20.1MPa in the PVT cell testing,17.93MPa in the full-diameter core testing,which showed that porous media has reduced the bubble point about 2.1MPa.
